Question

If of a square is 13 cm find its side​

Answer 1

Answer:

Let PQRS be the square of side x cm. ∴ PQ = QR = x cm …..(i) [Sides of a square] ∴ In ∆PQR, ∠Q = 90° [Angle of a square] ∴ PR2 = PQ2 + QR2 [Pythagoras theorem] ∴ 13 = x + x [From (i)] ∴ 169 = 2x2 The length of the side of the square is 6.5√2 cm.
